TL441AM - LOGARITHMIC AMPLIFIER

Description

This monolithic amplifier circuit contains four 30-dB logarithmic stages.

Gain in each stage is such that the output of each stage is proportional to the logarithm of the input voltage over the 30-dB input voltage range.

TL441AM LOGARITHMIC AMPLIFIER D Excellent Dynamic Range D Wide Bandwidth D Built-In Temperature Compensation D Log Linearity (30 dB Sections) . . . 1 dB Typ D Wide Input Voltage Range description This monolithic amplifier circuit contains four 30-dB logarithmic stages. Gain in each stage is such that the output of each stage is proportional to the logarithm of the input voltage over the 30-dB input voltage range. Each half of the circuit contains two of these 30-dB stages summed together in one differential output that is proportional to the sum of the logarithms of the input voltages of the two stages. The four stages may be interconnected to obtain a theoretical input voltage range of 120-dB.
